A rock on the Statehouse grounds holds two plaques related to the Boy Scouts: one commemorates the 75th anniversary of the scouts and the other recognizes an unknown boy scout who helped William D. Boyce navigate in dense London fog. When the boy refused a tip from Boyce because of his status as a scout, Boyce was so impressed he returned to the United States and was instrumental in starting the Boy Scouts of America. The true details surrounding the installation of the plaque are unknown but some attribute its placement to a ceremony celebrating Scouting's 25th anniversary in 1935.
